After cultivating the Azure Nether Divine Seal, his eight soul avatars had become two. Their qualitative improvement was beyond doubt, but the two soul avatars had not improved equally.
The outermost soul layer had roughly been formed by merging two of his original soul avatars. Its primary purpose was to pass itself off as his true soul and deceive the Origin Demons.
The second soul layer had been formed by merging the other six soul avatars. Its purpose was simple and brutal: to defend against all kinds of Soul Impact and demonic corruption.
Merging six soul avatars had not merely increased their defense sixfold, but more than tenfold. This was a quantitative change triggering a qualitative transformation. Without such a transformation, Chen Fei would have had no need to merge his soul avatars.
Now, as the first soul layer became demonized, the corruption seeped downward, only to be stopped immediately by the second soul layer.
Chen Fei observed the changes in the second soul layer. If the corruption penetrated too deeply, he would have to change his strategy, or even activate his panel backup outright to restore himself.
A moment later, a trace of a smile appeared in Chen Fei's eyes.
The combined effects of the Soul Void Sword Canon and the Azure Nether Divine Seal proved exceptionally powerful. At the current rate of corruption penetrating the second soul layer, it would take at least ten days or so to break through its defenses.
Even if the second soul layer's defenses were breached, that did not mean Chen Fei's true soul would immediately be corrupted. His true soul had defenses of its own.
However, that state would already be dangerous, so ten days effectively served as his critical limit.
Normally, ten days would be more than enough to cross the
